Downloaded File on kit

Hi,

I have a small c program (about 10KB) and I use the SDRAM as the program memory,heap,...etc. When I build my project, it says :

Linking Cfile.elf... 380KB (code+initialized data) & the rest of free memory in the SDRAM.

That makes a problem for its big size when storing it in memory (if I wanted to use memory bits for example). Why does the file have this big size?
